JOHN BRYAN, 0F YELLOW SPRINGS, OHIO.

PLOW.

T 0 all whom it may concern:

Be it known that I, JOHN BRYAN, a citizen of the United States, residingat Yellow Springs, in the county of Greene and State of Ohio, haveinvented certain new and useful Improvements in Plows, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

This invention relates to plows, and more particularly to means forconnecting the draft-hitch to the plow.

The object of the invention is to provide adjustable means forconnecting the drafthitch to the beam of the plow which can be actuatedby the operator from his position in the rear of the plow to cause theplow to turn a curved furrow; further, to provide connecting means whichwill be vertically adjustable to enable the angular relation of the plowshare to the surface of the ground to be controlled by the operator fromhis position in the rear of the plow; and to so construct the devicethat these two adjustments will not interfere one with the other andthat they may be made and used independently one of the other or bothmay be used simultaneously.

In the accompanying drawings, Figure 1 is a perspective view of a plowembodying my invention; Fig. 2 is a vertical, sectional view, taken onthe line 00 a; of Fig. 1; and Fig. 3 is a transverse, sectional View,taken on the line 3 3 of Fig. 2.

In these drawings I have illustrated one embodiment of my invention andhave shown the same as applied to a plow of well known construction.This plow comprises a share 1 having the usual beam 2 and handles 3.Mounted upon the forward end of the beam 2 is a connecting member forconnecting the draft-hitch to the beam. The drafthitch may be of anysuitable character and I have, therefore, here shown only the link bymeans of which it is secured to the connecting member, which isindicated at l. The connecting member, which may be of any suitableconstruction, is preferably a modified form of the usual clevis and islaterally adjustable relatively to the beam 2. As here shown thisconnecting member or clevis comprises a vertical arm 5 havingSpecification of Letters Patent.

therein a series of apertures (3. This arm has a rearwardly extendingsubstantially horizontal portion 7 provided at its rear end with a plateor bearing block 8 which is pivotally connected to the end of the beamto move about a vertical axis. This vertical axis is fixed againstlateral displacement and the arm 5 of the clevis is caused to travel inthe arc of a circle described about said axis. The bearing block orplate 8 is preferably secured to the beam by means of a supporting plate9 which is mounted on the beam and firmly secured thereto and to whichthe bearing block is connected by means of a vertical bolt 10 extendingthrough the two members. Suitable means are connected to the bearingblock 8 to move the same about its pivotal center and thus cause theclevis or connecting member 5 to be adjusted laterally relative to thebeam. This means is also preferably of such a character and is arrangedin such a manner that it can be operated by the plowma-n from hisposition in the rear of the plow. As here shown this connecting membercomprises an operating rod or shaft 11 mounted at its forward end inbearing lugs 12 secured to the supporting plate 9 and preferably castintegral therewith. This portion of the operating rod 11 adjacent to thebearing block 8 is provided with a worm 13 adapted to mesh with a wormgear 1 1 formed on the lower portion of the bearing block 8. Theoperating rod 11 extends rearwardly and its rear end is supported bymeans of a suitable bearing bracket 15 supported by the handles 3, and,in the present instance, carried by one of the transverse bars 16connecting said handles and forming a part thereof. The operating rod isalso provided at its rear end with a hand wheel 17, by means of whichthe rod may be readily rotated and the lateral position of the clevisand draft-hitch adjusted relatively to the beam.

By the proper adjustment of the drafthitch relatively to the beam theplow-share may be caused to travel in a curved line, thereby enabling acorner to be turned without removing the plow from the ground orinterrupting the furrow. The connecting member or clevis 5 may also bemade ad justable vertically relative to the beam 2 and this adjustmentlikewise may be controlled by the operator or plo-wman from his position in the rear of the plow, thereby enabling him to control the depthof the furrow. In the present instance this vertical adjustment isaccomplished by pivotally connecting the supporting plate 9 whichcarries the bearing block 8 and clevis 5 to the forward end of the beam2 upon a horizontal pivot extending transversely to the beam. To thisend the supporting plate 9 is preferably provided with two dependingflanges or lugs 18 arranged one on each side of the beam 2 and pivotallyconnected thereto by means of a bolt 19. The lugs or flanges 18 areconnected to the beam 2 at such a point that theplate 9 will besupported some distance above the upper edge of the beam, and,consequently, will be capable of a limited movement about the horizontalpivot or bolt 19. This movement may be imparted to the clevis and itssupporting members by means of the operating rod 11, and, to this end,the bearing bracket 15 for the rear end of the operating rod is shown asprovided with a series of bearing arms 20 arranged one above the otherand adapted to support the rear end of the operating rod in differentvertical positions and thus maintain the clevis and draft hitch in theirvertically adjusted positions.

The operation of the device will be readily understood from theforegoing description and it will be apparent that the plowman, from hisposition in the rear of the plow, may control the position of thedraft-hitch relatively to the plow beam and thus cause the plow-share totravel in a straight or a curved line and may control the degree ofcurvature. It will also be noted in this connection that theconstruction of the connecting member or clevis is such that the arm 7thereof will pass above the worm on the operating rod and its bearings,and, consequently, the clevis can be moved through an arc of the desirednumber of degrees, its movement being limited by a stop 21 secured tothe lower surface of the bearing block 8 and traveling in a groove 22formed in the upper surface of the supporting plate 9. Further, it willbe apparent that the plowman may also control from his position thevertical position of the clevis and the drafthitch relatively to the endof the beam and in this manner may control the depth of the furrow. Itwill be noted that these adjustments do not interfere one with the otherand that they may be used separately or simultaneously.

While I have herein shown and described a particular form of theinvention and have shown the same as applied to a particular plow itwill be understood that the invention may be applied to any type of plowand that the construction of the mechanism for adjusting the position ofthe clevis may be widely varied without departing from the spirit of myinvention as I consider myself the first to have provided means wherebythe lateral adjustment of the draft-hitch relative to the plow beam maybe made by the plowman from his position in the rear of the plow andwithout interrupting the movement of the plow. I, therefore, wish it tobe understood that I do not desire to be limited to the details ofconstruction shown and described, for obvious modifications will occurto a person skilled in the art.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is
